The 27-year-old, who only recently committed himself to a five-year contract, has seen his performances waver, with David Moyes calling for him to show a greater level of consistency.

Although the Portuguese winger has featured more regularly for United this season, clocking up 10 appearances as opposed to 21 for the entirety of last year, the winger is yet to become a permanent fixture for Moyes.

Juventus, along with Monaco, were touted as suitors last summer, but a deal failed to materialise.

But it seems Juve are undeterred and are willing to go back in for him again in January according to reports on the continent.
